Improvement in cultivators



UNITED STATES j JOHN BURNHAM AND WILLIAM O. LATHROP, OF LA SALLE, ILLINOIS.

IMPROVEMENT lN CULTIVATORS.

Specification forming part of Letters Patent No. dated September 11,1866.

.To all whom t may concern:

Be it known that we, JOHN BUnNH/lr/r and W. O. LATHROP, ot' La Salle, in the county of La Salle and State of Illinois, have invented a new and Improved Oultivator; and we do hereby declare fthat the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which- Figure l is a side view oi' our invention; Fig. 2, a plan or top view"of the same', Fig. 3, a det-ached front view of the main frame of the same; Fig. 4, a detached View of the coupling for the plow-frames pertaining to the saine.

Similar letters of :reference indicate like parts.

This .invention relates to a new and innproved cultivator of that class in which the plows are arranged so as to be adjustable both laterally and verticallygand it consists in a novel arrangement of the parts, as hereinat ter fully shown and described, whereby the device may be manipulated with the greatest facility, the team relieved ot weight on the neck, andlgthe device rendered capable ot' being converted into a single or double 011e for plowin g';"one or two rows of plants, as may be desired.

A represents an upright rectangular frame,

` to the lower ends of which wheels B B are atis well braced from the draft-pole G, and to the rear side of thefframe A there are secured, by joints b, two upright bars, F F, one near each end of frame A, the joints b admitting of the bars F turning to the right There are three plows, H, attached to each frame G, arranged in the usual way, and each frame is provided with a handle, I.

The two frames G G are connected by an arched or semicircular yoke, H", the ends ot' which are pivoted to bars I l, which are secured on the tops ot' the plow-frames G G by pivots 0, the b a-rs being allowed to turn freely on the pivots c.

By this arrangement it will be seen that the plow-frames are rendered capable of being moved up and down, orina vertical direction, and also capable ot' being moved laterally, or to the right and left.

The plow-frames are allowed to move up and down independently of each other, so that they may conform to the inequalities of surface over which they may pass; and the plows may be held up out ot' the ground by placing a hook,f, in the yoke IIX over an inclined bar, J, attached to the draft-pole O and frame A.

The lateral movement of the plow-frames admits ofthe plows being made to conform to the sinuosities of the rows of plants.

The mounted frame A prevents any weight bearing on the necks of the animals.

In using the device the plows of each frame work at opposite sides of a row ot' plants, the animals being in the spaces between the rows; hence one row will be plowed at each side, and the two adjoining rows at each side plowed at one side, which is equivalent to plowing two rows simultaneously.

If it be desired to plow only one row of plants at a time, the outer plows ot each frame G may be detached.

The duplex double-tree arrangement admits of an even draft.

Having thus described our invention, we claim as new and desire to secure by Letters Patent- 1. The attaching of the plow-frame G to an upright mounted frame, A, by means of joints d and bars F, arranged, as shown, to form a z met@ universal-joint connection, to admit of the verposed of the two double-trees D E, attached tical and lateral movement of the piows, snbto the draft-pole C, and connected bythe rods stent'ielly as described. a., substantially :is desorbed.

2. The connecting of the two piowfrnmes G The above specification of onr invention G by means of a lYoke, HX, having its ends signed by us this 14th dayof September, 1865.
